Application filed May 5, 1927. Serial No. 189,061,

This invention relates to acable bitch and more particularly to a type of hitch or grip adapted for use in fastening the loose end of a loop of cable for example such as is used for I guy wires, or the ends ofhauling cables passed around a thimble for making up emergency slings, and for tow ropes.

The principal object of the invention is to provide a hitch or grip which may be expeditiously installed and removed from engagements with the rope.

A clear conception of the operation and further objects of the invention may be had from the following specification in conjunction with the accompanying drawings in which;

Fig. 1 discloses the preferred form of the invention in plan view.

Fig. 2 is a side view of Fig. 1.

Fig. 3 is a cross-section through 3-3 of Fig. 1.

Fig. 4 is a plan view of a modified form of the invention.

Fig. 5 shows Fig. 4 in side elevation.

Fig. 6 shows a further modified form of the invention in plan view.

Fig. 7 is a side elevation of Fig. 6, and, FFig. 8 is a cross section through 88 of The now preferred form of the invention consists of a metal block 1, formed with L shaped slotted lugs 2, 3, and 4 on one of its faces and the lugs 5 and 6 on its opposite face. The lugs 2, 3, and 4 are similar in construction and are shown in cross-section in Fig. 3; lugs 2 and 4 are set with their slotted portions facing in the same direction, while the slotted portion of lug 3 faces in the opposite direction, thereby forming a tortuous path through which the body 7 and end portions 8 of the cable are passed. The edges of the slotted portion of lugs 2, 3, and 4 may be made square to create as much friction as possible between the lugs and the cable. When the loop of the cable is passed about an object, and the hitching device set in lace, and the cables put under a strain the friction between the cable portions 7 and 8 and lugs 2, 3, and 4 is suflicient to hold the cable in a tight grasp, thereby forming a non-slipping hitch or loop.

The lugs 5 and 6 are for facilitating the application of the device to cables that are under strain such as guy wires, and therefore hard to bend into the line of the tortuous path. A rod or special tool (not shown) may be used which will co-operate with the lugs 5 and 6 thereby turning the hitching device in such manner as to catch the lugs 2, 3 and 4 about the cable.

A modified form of the invention is shown in Figs. 4 and 5 and consists of a bar 8 having lugs 9 and l0'formed on one side thereof. These lugs are formed and positioned in the same manner as lugs 2 and 3 of the preferred form thereby forming a tortuous path. The end 12 of bar 8 is formed with a thimble l4 thereon, around which the cable 11 is looped.

Midway between the thimble 14 and the lug 10, retaining members 16 and 17 are formed on the bar 8, thereby forcing the cable to follow a tortuous path and also keeping the cable from jumping out of the grooves in thimble 14. The friction caused by the lugs 9 and 10 and the spacing members 16 and 17, and between the body 11 and 15 of the cable, is suflicient to keep the cable from slipping. This type of hitch may be used as a hauling rope and sling or in any of the many operations for which the thimble is used.

A still further modified form of hitch is shown 'in Figs. 6, 7 and 8, which comprises a block 18 formed as shown, with lugs 19 and 20 at each end thereof. A hole is formed in the center portion of block 18 for accommodating the hook bolt 21. The threaded end of hook bolt 21 is peaned over to prevent nut 24 from being removed, thereby insuring that the parts, i. e., the base, bolt and nut, will not become separated.

The end 22 and body 23 of the cable are positioned under the loops of bolt 21 and between the lugs 19 and 20 with the end 22 of the cable resting against the base 18. The bolt 21 is then tightened by means of nut 24 until the cables are held snugly together in a tortuous path thereby forcing the end 22 and body 23 of the cable into frictional engagement with the block 18. It is apparent that this type of hitch may be used with a thimble in a manner similar to that described above.

I claim:

1. A hitch of the type described comprising a base with a plurality of holding members thereon, said members being positioned to hold a pair of cables side by side in the same plane and cause the cables to be displaced from a straight line in said plane at the center of said base, thereby bringing said cables into frictional engagement with one another and with the holding members to hold said cables from slippage.

2. A hitch of the type described comprising a base with a thimble formed thereon, said base having a plurality of holding members integral therewith to hold the ends of-a cable passed around the thimble, said ends being allocated by said holding'members in the same plane and in contiguous relation, said holding members causing said ends to be displaced from a straight line at the centerof said base, thereby bringing the cables into frictional engagement with one another and with the holding members in a suflicient degree to hold said ends from slippage. I 3. In a hitching device of the type described, abody portion having a plurality of slotted lugs thereon positioned to form a tortuous path through which cables may be passed to form anon-slipping hitch.

45. In a hitching device of the type described, a block of metal having a plurality of slotted lugs thereon positioned to form a tortuous path through which cables may be passed to form a non-slipping loop, said lugs having sharp edges to give frictional engagement between said lugs and said cable.

5. In a hitching device of the type described, a block of metal having a plurality of square slotted lugs thereon positioned to form a tortuouspath in which cables may be held by friction to form a non-slipping hitch. 6. A hitch, of the type described comprising a base having spaced holding means thereon, said holding means being positioned to hold a plurality of cable parts side by side in the same plane and cause said cable parts to be displaced from a straight line in said plane at the center of said base, thereby bringing said cable parts into frictional engagement with one another and withthe holding means to hold said cable parts from slippage.

In testimony whereof I have signed this specification.
